Hello,

I want to build the boost libs on my system (os: Windows 10 Pro 32 bit). 
My build command is:
b2 -j2 --build-dir=D:\boost_1_67_0\boost_1_67_0\Build toolset=gcc 
variant=debug link=static --build-type=complete stage
But the problem is: I get errors like "sorry, unimplemented: 64 bit mode 
not compiled in" as you see for example in this screenshot:

Any ideas? Thanks!
